Best of Last Week–Can space travel faster than light, another planet behind the Sun and should we allow head transplants

(—It was an interesting week for physics research—most of the big news was centered around space, the cosmos or how things came to be as they are. One team of physicists offered a solution to the puzzle of the origin of matter in the universe—suggesting that matter-antimatter asymmetry could be related to the Higgs boson particle. Another team wondered, how can space travel faster than the speed of light? If nothing can travel faster than light, they asked, how is it possible that there are parts of spacetime where the photons that make up light are forever out of our reach? And yet another team wondered if classical theory could be just as weird as quantum theory—they showed that objectivity, determinism, and independence are mutually incompatible with any theory. —> Read More Here
